Changes in the seam-filtration mode with stress redistribution in country rock

A mathematical model for the mechanism of increasing oil output of productive seams is developed. The model involves a deliberate “conversion” of segments of the fault zone of the country rock to a supercritical state, which leads to a local redistribution of stresses in the block massif of rocks and an increase in contour and seam pressures. Based on solving the problem of restricted filtration, it is shown that the use of the proposed mechanism can ensure a relative increase in well production of 5–8%.
